The act of mixing chemicals is a physical process, not a chemical reaction. Mixing chemicals together may, or may not, allow a chemical reaction to proceed, depending on the nature of the chemicals being mixed.
- forming a homogeneous solution- forming a precipitate by chemical reaction- sedimentation of an insoluble phase, without chemical reaction
The simple act of mixing chemicals can be a physical one if they do not react. For it to be a chemical change a reaction has to occur and it has to have a change in odor, color, temperature, or has the formation of gas or a precipitate to technically have changed chemically.
When two chemicals bubble upon mixing, it typically indicates a chemical reaction is taking place. The formation of gas bubbles usually suggests a release of gas as a product of the reaction. This observable change is a common indicator of a chemical transformation.
No, fizzing after mixing two chemicals is a chemical change.
by mixing to chemicals
a chemical reaction is a reaction were the two chemicals change into a new chemical.
Adding a base to an acid or vice versa in changing the chemical properties of that solution. In both cases you are neuralizing the solution. There might be a physical change as well, but it would depend on what chemicals where mixing. But this reaction will definitely have a chemical change.
No, mixing cornstarch with water is not a chemical reaction. It is a physical change. The cornstarch particles disperse throughout the water, but no new substances are formed.

That depends on the chemicals present before the chemical reaction and sometimes the conditions under which the chemical reaction occurred.
One or more products are formed in a chemical reaction.
